I also couldn't get sbcl to emerge either until I set USE="-threads" for it.

@The Doctor => have you been able to emerge it by now? or just gave up?

I've look inside the slime.texi and it seems (like it sais) that there is an error on the line 536 (Where it sais @itemx should follow @item). I've read somewhere that this used to be a warning. Changing it to @item instead makeinfo only prints the two remaining warnings._________________If it moves, compile it!

I gave up on it. I was running clfswm, but I moved to i3 so lisp became something to have fun with rather than an important part of my system._________________First things first, but not necessarily in that order.

Please try adding this line to /etc/portage/package.use (if you agree to the
xref license, as that avoids us having to rm the xref.lisp file, which
is presumably useful for something since it is included in the distribution):

Code:

app-emacs/slime xref

And this line to /etc/portage/package.keywords:

Code:

<app-emacs/slime-9999

Then (after syncing the lisp overlay), please try:

Code:

emerge -av =app-emacs/slime-2.0_p20130930

slime upstream have not updated the ChangeLog for a while, so when it loads
it says it is an old version. I have to patch this hardcoded date of the last entry
in the ChangeLog in slime.el to avoid the "versions differ" warning on startup

Since there were changes in the slime cvs log that are not noted in the ChangeLog,
I thought it was less confusing to hard code the date to a later date. So now
app-emacs/slime-2.0_p20130930::lisp says:

Lisp ain't an important part of my system (yet), but still, working with slime from emacs grows on you, rather than loading / dumping / reloading your files every time. As of now I kind of play with lisp myself. Got me 2 books and I'm trying to get proficient with lisp and rely on it for small tasks as I go along. I had another system a while ago (gentoo as well) and there it worked like a charm. Had emacs daemonized, my files open, and with slime it was just glorious and enchanting to work and learn lisp._________________If it moves, compile it!

It would be neat if you could please test and let us know the results. As I have a different
version of texinfo and it worked for me without this change, so I don't know if the change
will work or not (I am hopeful).
